EOS R5 - Time-lapse movie stops recording and does not save footage

[CreateLikeAPro]

Hi I'm trying to record movie time-lapses with the R5 with the RF 28-70 F/2 and RF 16mm 2.8, it randomly stops and does not save the footage, after it stops and fails to record I check movie time-lapse settings and it's disabled.

Settings are
Time-lapse: enabled
Interval: 4, 5, 10 (Tried a few)
No. of Shots: 300, 1000, 3600 (Tried a few)
Movie rec. size 4K-U
Auto exposure: Each Frame
Screen auto off: Enable, Disabled (Tried Both)
Beep as img taken: Enable, Disabled (Tried Both)
With interval 4 at 300 shots shows: Record time 00:19:56  |  Play time 00:00:10

Firmware: Ver. 2.1.0

Battery: Fully Charged
Power Saving
Display off: 10 min
Auto power off: 10 min
Viewfinder off: Disable 
Eco Mode: Off

I'm using a CFexpress B card, AV PRO SE 512 GB 1785 MB/s, Formatted

If I take photos with the interval timer it works fine but would also like to be able to use the video time-lapse function as well. Any help would be greatly appreciated. If you need more information regarding settings, please let me know.

Thank you!
Louis

Greetings CreateLikeAPro,

Let's check a few settings to see if we can find the cause of this issue where the camera is randomly stopping and not saving the time-lapse movie.

I understand that you state the intervals you have tried are like 4, 5, and 10 but unsure if you are referring to seconds, minutes, or hours. The intervals reflect the amount of time where it's set to hours : minutes : seconds. For testing, let's test to see if we can set the interval to 10 seconds. Please note that an interval of once per second is not available.

Then, let's set the number of shots to about 100. This would have the camera take six shots per minute if the interval is set to 10 seconds, and it would shoot for 10 minutes. The final video should provide us with about a 2 second clip, which is short, but would let us see if it was able to record and save the video. I would suggest to also set the Auto exposure to Fixed 1st frame. Let's shoot outdoors or in a very bright environment where the camera is able to process images faster before the next shot needs to be taken.

Hi Natalya,

Thank you for the reply, I was referring to 4, 5, and 10 seconds. I was successfully able to record using the following settings.

10 second interval 100, 200 and 300 shots (Auto Exposure: Fixed 1st frame), shutter speed 1/100
8 second interval 200 shots (Auto Exposure: Fixed 1st frame), shutter speed 1/100
6 second interval 200 shots (Auto Exposure: Each Frame), shutter speed 1/100
5 second interval 150 shots (Auto Exposure: Each Frame, shutter speed 1/60

None of these had moving subjects, not sure what caused the other time-lapses to fail. Need to run more tests and will get back to you.

Thank you,
Louis
